FIX: Sound does not come from a Bluetooth-enabled audio device as expected on a Windows CE 5.0-based device that supports A2DP

You plug a paired Bluetooth-enabled audio device into a Windows CE 5.0-based device that establishes an Advanced Audio Distribution Profile (A2DP) connection. However, when a sound is played, the sound does not come from the Bluetooth-enabled audio device as expected. Instead, the sound comes from the local audio of the Windows CE 5.0-based device. For example, the sound may be a system sound alert or the sound that comes from Windows Media Player.
